SPECIFICATION forming part of Letters Patent No. 237,982, dated February22, 1881.

Application filed September 28, 1880. (No model.)

To all whom it may concern: the slot fitting the bolt, said bolt and nutare Be itknown that I, HUGH S. JOINES, a citiheld fast withoutpossibility of turning. zen of the United States, residing at Santa Fe,The device is very simple in construction, in the county of Santa Fe andTerritory of easy of application, and efficient in use. 5 New Mexico,have invented certain new and The boltA having been passed through theuseful Improvements in NutLocks and I do articles to be secured, thenutBis screwed therehereby declare the following to be a full, clear, onto the proper position. The cap (l is then and exact description of theinvention, such as placed over the projecting end of the bolt and willenable others skilled in the art to which it forced down into closecontact with the face of 10 appertains to make and use the same,reference the nut, and the inwardly-turned flanges d, by being had tothe accompanying drawings, and the same movement, pressed over the edgesof to letters or figures of reference marked therethe nut and sprungintothe beveled sides thereon, which form a part of this specification. of,where they are firmly held bytheir spring- This invention consists in anut having each like action and the peculiar form of the sides 15 of itsfour outer sides beveled or recessed, and of the nut, and as the edgesof the slotted pora sheet-metalcap or washer having at each end tion ofthe cap bind against the flattened porau inwardly-turned flange, toengage with the tion of the bolt, both the bolt and nut are sebevels ontwo sidesof the nut, andaslotthrough curely held from turning so long asthe cap rewhich the end of the bolt projects, the bolt bemains inposition.

In this construction the nut B graduallytapers from the top to near the bottom, where such taper terminates in agroove or recess, 1). The sheet-metal cap 0 has an elongated slot, 0, asin the before-mentioned construction; but in lieu of the downturnedcorners of the cap resting upon and embracing the edges of the nut, asin Fig. 1, they may extend beyond said edges, as shown in Fig. 4., so asto be out of close contact with the nut at those points, and at the sametime increase the facility with which said cap may be removed, as thespace in which the raising-tool would be inserted is larger than in thepreceding example. The flanges d are inturned, as in the otherconstruction, and spring into recesses I) in the sides of the nut.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The nut B, having its outer sides beveled or recessed at b, and thesheet-metal cap 0, slotted at c, to receive the bolt, and havinginwardly-bent flanges d d, to engage with said beveled nut,substantially as and for the purpose set forth.

2. The combination of an irregularly-shaped bolt, A, nut B, havingbeveled sidesb, and the cap 0, having slot 0 and inwardly-bent flangescl, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
